Estimation Of Starch In Plant Tissue , Robert Delafield Powell

Retrospective Theses and Dissertations

The various factors affecting the estimation of starch by determining the glucose formed by acid hydrolysis following enzymatic hydrolysis have been studied. The effect of grinding of the plant material was shown to be important. Insufficient grinding leads to low values in starch, and grinding in the ball mill caused a breakdown of starch, and probably of non-starch interfering substances, to more soluble material;Gelatinization is necessary to extract starch from plant tissue. Probably vigorous conditions are not needed, but autoclaving for one hour at 15 pounds had no detrimental effect on starch recovery;Salivary diastase is preferred to taka-diastase ...
